The Bomag 05722212 Piston Ring Set is a genuine OEM component designed for the BP 20/48 D and BP 23/48 D vibratory plates, the BPR 30/38 D reversible vibratory plate, and the BW 71 E walk-behind roller. Sourced directly from Bomag, this piston ring set delivers an exact match to the original engine specification, ensuring a correct seal between the piston and cylinder bore with no guesswork on fitment. If your compaction equipment is showing signs of excessive oil consumption, loss of compression, or reduced engine power, replacing the piston ring set with a genuine OEM part is the right first step to restoring full performance.
Key Features
- Genuine OEM Compression Integrity — manufactured to the same tight ring-gap tolerances as the original, maintaining proper cylinder seal and combustion efficiency in diesel-engine compaction equipment
- Drop-In Engine Fitment — engineered to match the original piston and cylinder bore dimensions, allowing direct installation without machining or adaptation
- Broad Compaction Equipment Coverage — fits the BP 20/48 D and BP 23/48 D vibratory plates, BPR 30/38 D reversible vibratory plate, and BW 71 E walk-behind roller under a single part number 05722212
- Restored Engine Output — worn or broken rings allow combustion gases to bypass the piston, robbing power and increasing fuel consumption; a fresh ring set brings compression back to spec and keeps the engine pulling its rated load
- Verified Bomag Part Number — order with confidence knowing part number 05722212 is the correct OEM reference for these machine models, eliminating the risk of ordering a mismatched set
A piston ring set forms the critical seal between the moving piston and the cylinder wall inside the engine. The rings control oil consumption, maintain compression pressure for reliable combustion, and transfer heat away from the piston into the cylinder wall. When rings wear, break, or lose tension, compression drops, oil burns into the combustion chamber, and the engine delivers noticeably less power — symptoms that become immediately apparent in demanding compaction work. Replacing the entire ring set restores the compression seal and allows the engine to operate at its intended output.
